Embodiment Construction

[0016] The present invention will be specifically introduced below in conjunction with the accompanying drawings and specific embodiments.

[0017] Such as figure 1 The shown cutting spindle structure includes: a main shaft 10 and a cutting blade 20, the main shaft 10 includes: a main shaft housing 11, an air bearing 12 located in the main shaft housing 11 and an air bearing between the main shaft housing 11 and the air bearing 12 Cooling water13. The air bearing 12 has low friction and low temperature, and the cooling water 13 is used to cool down the rapidly rotating air bearing 12. The air bearing 12 and the cutting blade 20 are connected by a rotating shaft 120, and the inner surface of the main shaft housing 11 is provided with a temperature sensor 110, and the temperature sensor 110 is connected with a controller for controlling the switch of the air bearing. Close the air bearing 12 when the temperature is too high.

[0018] The main shaft housing 11 is provided with...

Abstract

The invention discloses a cutting spindle structure which comprises a spindle and a cutting blade and is characterized in that the spindle comprises a spindle casing, an air bearing arranged in the spindle casing and cooling water arranged between the spindle casing and the air bearing. The air bearing and the cutting blade are connected through a rotary shaft, a temperature sensor is arranged on the inner surface of the spindle casing, and the temperature sensor is connected with a controller for controlling an air bearing switch. The cutting spindle structure has the advantage that the air bearing can reduce friction of rotation of the spindle, and a temperature rising range is reduced to the maximum degree by means of stable air flow and effective power transmission. The cooling water further reduces working heat of the spindle and prolongs the service life of the spindle.

Description

technical field [0001] The invention relates to a cutting device of a cutting machine, in particular to a cutting spindle structure. Background technique [0002] The core unit of the cutting machine is the cutting blade, which is connected with the main shaft, so the main shaft unit is an important part to realize the cutting function. The main shaft is the meaning of the axis of rotation, which is used to drive the blade to rotate. During the rotation process, heat is generated due to the friction of the bearing, which affects the working efficiency and life of the spindle. Contents of the invention [0003] In order to solve the deficiencies of the prior art, the object of the present invention is to provide a cutting spindle structure which can prevent the spindle of the cutting machine from overheating. [0004] In order to achieve the above object, the present invention adopts the following technical solutions: [0005] The cutting spindle structure includes: a ma...
